Preheat the oven to 190°C. Lightly grease a 23x33 cm baking dish.

In a large mixing bowl, combine the sliced peaches, granulated sugar, brown sugar, lemon juice, cinnamon, nutmeg, cornstarch, and a pinch of salt. Toss gently to thoroughly coat the peaches.
03 -
Transfer the peach mixture to the prepared baking dish, spreading evenly.
04 -
In a separate bowl, whisk together the flour, sugar, baking powder, and salt. Add the cold cubed butter, and use a pastry cutter or your fingertips to work the butter into the dry ingredients until the mixture resembles coarse crumbs.
05 -
Pour in the milk and vanilla extract. Stir just until combined; do not overmix. The dough should be soft and slightly sticky.
06 -
Spoon dollops of biscuit dough over the peach filling, leaving some gaps to allow steam to escape.
07 -
Sprinkle the remaining granulated sugar over the topping. Bake for 40–45 minutes, or until the topping is golden brown and the filling bubbles at the edges.

Allow the cobbler to cool for at least 15 minutes before serving. Serve warm, optionally accompanied by vanilla ice cream.
